Asked by Karen
Find the domain of each function.
And show your steps please.
f(x)=x/x^2+1
f(x)=2x^2/x-3
f(x)=Square root of 5-x
f(x)=x^3/x^2-16
And show your steps please.

polynomials have domain of all reals
rational functions have domain of all reals except where the denominator is zero
sqrt has domain all x>=0
